1 Claim. c1. 4-134 This invention relates to an invalids commode, and it particularly relates to a commode comprising part of achair which can be placed next to a bed lin a position where the patient can easily move onto it. i

The use of bed pans for bed-ridden patients is something which most people, both patients and attendants,

Where the patient would prefer to avoid if possible. cannot be moved at all, the use of bed pans is usually unavoidable; however, if the patient can sit up at all, it is usually possible for him to slide from his ,bed into a chair set at the same level as the bed. Such a'chair,hav-

ing a commode thereon, makes it much more agreeable ever, none 'of the prior types ofxchair commodes have adequately served the purpose, being either too complex and bulky to be easily handled by the invalid or too flimsy and unreliable to adequately support the invalid while permitting eifective use.

It is one object of the present invention to provide an invalids commode device which is simple enough to be effectively manipulated by the patient while being, at the same time, effective for its purposes.

Another object of the present invention is to provide a chair-type commode which is safe for holding a bedriddenpatient while it is yet movable toward and away from the bed.

A further object of this invention is to provide a commode chair which is at least partially foldable or collapsible so as to occupy a minimum amount of space while in storage.

Other objects of the present invention are to provide an improved commode device, of the character described, that is easily and economically produced, which is sturdy in construction, and which is highly efiicient in operation.

With the above and related objects in view, this invention consists in the details of construction and combination of parts, as will be more fully understood from the following description, when read in conjunction withthe accompanying drawings in which:

Referring now in greater detail to the drawings wherein similar reference characters refer to similar parts, there is shown a chair type commode, generally designated 10, which comprises two oppositely disposed tubular frame members 12 and 14 having similar tubular depending legs 16 on each end. These legs 16 each telescopically receives a rod '18, these rods 18 being adjustably secured to their respective legs 16 by means of clamping sleeves,

suchas shown at 26. These clamping sleeves of split design are each provided with a pair of ears 22 apertured to receive a set-screw 24. A nut 26 is positioned against the outer side of one of the ears 22 to hold the screw 24 in clamping position.

At the lower end of each rod 18 is provided a bracket 28 of inverted U-shape and in each of these brackets is journaled an axle 30 upon which is rotatably mounted a Wheel or roller 32. Extending between the rods 18 at each side of the chair is a rod 34 adjacent each end of which is pivotally connected as at 35, a brake arm 36 having a brake shoe 38 at its lower free end. Each brake shoe 38 is adapted to frictionally contact the periphery of a wheel 32. The toggle brakes constituted by the arms 36 and brake shoes 38 are operated by a foot pedal 40 pivotally mounted by means of a lever 42 to a corresponding rod 34 on each side of the device; each lever 42 beingpivoted to its corresponding rod 34 by a pivot pin 44. Each lever 42 is also pivotally connected, as at 46 and 48, to a pair of oppositely-extending links 50, each link being pivotally connected at its other end to the corresponding brake arm 36, these pivot connections to the brake arms being indicated at 52. By means of this construction, the wheels 32 can be held in braked position when the device is in place merely by stepping on each brake pedal 40. When it is desired to release the brakes, the pedals 40 are merely pulled up. The offcenter arrangement of the pivots 46 and 48 causes the brakes to be retained in the position in which they are put.

At the upper portion of the device, a plate 54 overlies the two tubular frame portions 12 and 14 and is provided with a curved peripheral flange or lip 56 which partially encompasses the frame members 12 and 14 on each side of the device and also extends around the front and rear. In the center of the plate 54 is a toilet opening 58 which is surrounded by a toilet seat 60. The seat 60 is releasably held in position by guide lugs 62 on top of the plate 54. Angled bracing struts 64 extend from the legs 16 to the adjacent undersurfaces of the plate 54 to bracingly support the plate.

Underneath the opening 58 is a deep pan 66 having an upwardly and rearwardly inclined bottom (as best seen in Fig. 1). This pan 66 is releasably held in position by means of a retaining assembly comprising a generally U-shaped yoke 68 the upper ends of which are connected to the undersurface of the plate 54 by means of rivets '70 or the like. At the center of the yoke 68 is provided an aperture mating with internally-threaded bore of a boss 72. Through the bore of boss 72 and through the mating aperture of the yoke 68 extends a screw 74 having a head 76. The upper end of screw 74 is engaged in a recess in the undersurface of a bearing member 78 which bears against the undersurface of a clamping plate 80. The clamping plate 80 bears against the undersurface of pan 66 to press the pair 66 tightly against plate 54 under- ,mounted on forwardly-extending arms .84 supported by angular brace bars 86 (as best seen, in Fig. 1).

Pivotally connected to frame members Hand 14, was at 88 and 90, are the flattened ends 92 and 94 of a pairpf tubular arms 96 and 98, these tubular arms being integrally connected by a cross-arm 100 at the top. A cushioned back rest 102 has its lower end pivotally secured to a rod 103 extending between the arms 96 and .98 while its upper end is releasably connected to the cross-bar.100

bya latch means 104. By this construction either the entire back assembly, includingthe arms 96, L98and 1fi0 and the back rest 102, or the back rest 102, by itself,.may

be hingedly b rought down to cover the opening 58 and seat 60.

Apair of arm rests, one on each side of the chair,. are

formed by bent tubular rods.106. Each of the rods 106 has a flattened rear end 108 apertured to receive a threaded bolt 110. Each bolt 110 extends through an arm 96 or 98. A wing nut 112 holds the bolt 110 in place. The opposite end of each rod 106 is releasably held in a socket 114 depending from the front end of each of the frame members 12 and 14. A guard member 116 is provided on each rod 106.

In use, the chair is pulled up to the side of a bed, the height of the legs are adjusted so that the device is at ,thesame level as the bed, the brake pedals 40v or either one thereof is stepped on to lock the wheels in place, and

, the arm rests 106 are removed from their sockets 114 and raised on the pivots formed by bolts 110. The pa tient ,can; then slide onto the chair and the front ends of the .armrests A 106 can. then be placed in the sockets 114.

After use, the arm rests are lifted up, the patient. slides back into bed, and the attendant can then lower the back rest assembly andremove the chair to a disposahpoint where the pan 66, is removed and cleaned,

Although this invention has been described in considerable detail, such description is (intended as being illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined as claimed.

Having thus set forth and disclosed the nature of this invention, what is claimed is:
